Abstract: 408,776. Switching systems for consuming devices and batteries. WIEGEL, P. H., 58, Merwedestraat. The Hague. Feb. 2, 1933, No. 3240. Convention date, Feb. 2, 1932. [Class 38 (iv).] The earthed terminal of a battery 1 on a motor vehicle is connected to the chassis through switch contacts 7 controlled electromagnetically by a switch 6 for the consuming apparatus so that the battery is disconnected from the chassis when the consuming device 5 is disconnected. Switch contacts separately controlled by switches connecting up separate groups of consuming devices, may be connected in parallel in the earth connection. In a modification, a switch 21<1> in the earth connection, the contacts of which are in parallel with those of a switch 22, is closed mechanically by the action of the switch 22 when an ignition coil 14 is energized and maintained closed after the opening of the circuit of the ignition coil so long as other consuming devices such as lamps controlled by a switch 11 are in use. In a modified form of this arrangement the coils and cores operating the contacts of the switches 21<1>, 22 are concentrically arranged and a compression spring between them operates the contact of the switch 21.'

Abstract: 305,145. British Thomson-Houston Co., Ltd., (Assignees of Bany, H.). Jan. 31, 1928, [Convention date]. Synchronizing dynamo-electric machines; systems depending on two or more machines; switching systems.-The voltage of an exciter which is controlled, as by a Tirrill regulator, so as normally to maintain a given voltage on the dynamo-electric machine which it excites is maintained above normal during the starting of this or another machine so that it shall be adequate for the carrying out of switching operations associated with the starting and paralleling of that machine. The exciter 8 which supplies the fields 6, 7 of synchronous generators 1, 2 is controlled by a Tirrill regulator 11 to maintain a given voltage on the load circuit 3. Assuming one machine, say 1, to be on load the closure of a switch, say 15, to start the second, in addition to operating a masterrelay 17 which eventually causes the main switch 5 to close, also energizes a relay 29 should the exciter volts be insufficient to hold contacts 30 of an exciter-voltage relay open. The relay 29 energizes a relay 28 which inserts an impedance 26 into the load circuit of the exciter and causes the regulator 11 to increase the exciter voltage. The impedance 26 is again short-circuited when the field switch 10 is closed, an operation which is effected by the main switch 5 when putting the machine 2 in parallel with machine 1 and by which the machine 2 is pulled into synchronism. Separate impedances may be used in each field circuit. In a modification in which a generator is synchronized before paralleling, an impedance in the field circuit is short-circuited only when the paralleling switch is closed.

Title: Apparatus for the manufacture of extruded elements from plastic masses, for example clay
IPC: A45D20/10
Filed: 1966-01-27
Abstract: 1,087,502. Shaping extruded tubing. F. SEIBERT & P. SEIBERT. Jan. 27, 1966, No. 3737/66. Heading B5A. Shaped tubular elements, e.g. packing elements, of plastic material such as clay are produced by extruding a tube of the material through guide tube 5a from an extrusion crosshead 1, and subsequently through a shaping device 3, a guide tube 5b, the zone of action 48 of a vertically reciprocable cutting device 4, and finally through a guide tube 5c, both the shaping device 3 and cutting device 4 being mounted for limited movement at the speed of and in the direction of extrusion. Shaping device 3 produces apertures or inwardly directed projections in the extruded tube, Figs. 4, 5 (not shown), by mechanism actuated via a cam 35, cam follower 36 and levers 37, 39. Simultaneously device 3 is moved horizontally in the direction of extrusion by co-operation of cam 15 with cam follower 14 with consequent rocking of lever 13 and movement of shaping device support 10 and guide rod 7, which latter slides in bearings 8. Cutting device 4 which comprises a horizontal wire 47, see also Fig. 2 (not reproduced), is mounted to move horizontally with guide rod 7, its cutting movements being produced by co-operation of cam follower 42 with cam 41 and a spring 49 which moves the device upwards when cam 41 releases follower 42. Cams 15, 35 and 41 are driven from a common shaft 17 and their speed of rotation and relative angular dispositions are adjusted to give the desired sequence of operations, e.g. as shaping device 3 is forming apertures or projections, wire 47 cuts the preceding completed portion of the extruded material. Cross-head 1, which is connected to a piston impeller, contains a hollow mandrel (23) Fig. 3 (not shown), and die plate (22), the former housing a rod (26) which is connected via an arm (29) and link (30) for reciprocation with shaping device (3). Further, rod (26) supports a core (21) which prevents buckling of the extruded tube during operation of shaping mechanism (19), (20) and has bores (31), (32) so that oil may be distributed to lubricate the inner surface of the tube. The outer surface thereof is lubricated via an annular groove (33). By disengaging link 30, Fig. 1, from arm 29 and retracting rod 26 to remove core 21 from device 3, cross-head 1 may be removed from the body of the extruder to facilitate filling thereof. Also, cross-head 1 may be dispensed with and an extruder utilizing a hollow screw to accommodate mandrel (23) may be used.
